The ATA65XX family adds six new devices to Microchip’s CAN portfolio, supporting the recently established CAN FD (Flexible Data-rate) protocol for up to 5 Mbit/sec communication speed and the new CAN PN (Partial Networking) standard for improved energy efficiency for vehicles. The devices are fully compliant with the ISO 118980-2/5/6, 11898-2:2016 and the SAE J2962-2 standards. The ATA6562, ATA6563, ATA6564, ATA6565 and ATA6566 are presented as the first automotive Grade 0 qualified CAN/CAN FD transceiver family with an ambient temperature rating of -40° to 150°C.
Microchip also provides a CAN Partial Networking transceiver including a window watchdog. The devices are approved by major car manufacturers for use without the external Common Mode Choke (CMC) that is required for most CAN transceivers.
All family members include wake-up capability via CAN bus with dual wake-up pattern according to ISO 11898-2:2016. A modern vehicle contains more than 70 Electronic Control Units (ECU) with CAN interface. This feature avoids unwanted power-up sequences, leading to significant energy savings and reduced emissions. The ATA65xx family is supported by the ATA656x-EK development kit, ATAB6570A development kit and the ATA6563 Click Board. The parts are in
SO 8/14 and DFN8/14 packages with wettable flanks, ready for automatic optical solder-joint inspection.
